"26th International Technical Meeting of the Satellite Division of the Institute of Navigation" . "Network RTK is a widely used method for GNSS signal augmentation. With respect to the pure RTK method based on processing of phase and code measurement from a real reference station, network RTK brings many advantages -lower demand on reference network density contributing to significantly reduced infrastructure costs, higher robustness, and reduction of some station dependent errors. Several concepts for network RTK have been developed and are used widely nowadays: VRS, FKP, MAC, reverse RTK. GPS Solutions (GPSS) has developed and implemented a new complete system for network RTK consisting of all necessary components: data gathering part, processing center & corrections data generator, NTRIP front-end in-terface for RTK clients, and a web-based GUI for system administrators. We call this system RTRef. In the RTRef system we place the maximum emphasis on precise modeling of systematic errors, mainly the tropospheric and ionospheric delays. Receivers of various manufactures are supported. Since our RTK system supports GPS, QZSS and Glonass satellite systems, inter-system and receiver specific inter-frequency biases for Glonass observations are estimated among numerous other parameters. The aims of this paper are to introduce our RTRef system and to demonstrate its capabilities. Because great attention was being paid to the processing of Glonass observation, the topic of ambiguity resolution for Glonass and the impact and importance of Glonass on RTK solution precision and robustness are discussed."@en .
